Is the “new” history of capitalism all that new? 1 Business historians and economic historians
who have toiled away for decades are likely to answer in the negative. And for good reason:
much of the scholarship that parades under the history of capitalism banner seems, with some
subtle differences, to resemble the work done by an earlier generation of scholars. A cynic could
be forgiven for thinking that the only significant difference between the new and old scholarship
is that the mainstream historical profession now seems to agree that studying corporations,
finance, and capitalists is now cutting edge, and thus worthy of widespread recognition in the
form of awards, tenure-track jobs, and other professional accolades.
There is reason to be skeptical. In the spirit of that skepticism, I wish to engage with that
older literature, as well as the very real criticisms that have been leveled at it by succeeding
generations of business and economic historians. And I wish to propose another way – though
by no means the only way – of understanding the critical developments of nineteenth century
capitalism that moves beyond both the traditional preoccupation with the firm as the preferred
unit of analysis and the belief that the “managerial revolution” as the defining development of
the second industrial revolution. Whether this constitutes anything particularly “new” is
something that I will leave to the reader to decide.
In so much of the literature in traditional business history, the twin focus on the firm and
on management very much originated in the work of Alfred D. Chandler, Jr.. In his signal works
– Strategy and Structure, The Visible Hand, Scale and Scope – Chandler framed the story of
modern capitalism as a triumph of organization.2 In sometimes excruciating detail, Chandler
1 For meditations on this question, see Sven Beckert, “History of American Capitalism,” in Eric Foner and Lisa McGirr, eds., American History Now (Philadelphia: Temple University Press, 2011), 314-335; Louis Hyman, “Why Write the History of Capitalism?” Symposium Magazine, 8 July 2013. 2 Alfred D. Chandler, Jr., Strategy and Structure: Chapters in the History of Industrial Enterprise (Cambridge, Mass.: Harvard University Press, 1962); The Visible Hand: The Managerial Revolution in American Business (Cambridge, Mass.: Harvard University Press, 1977); Scale and Scope: The Dynamics of Industrial Capitalism (Cambridge, Mass.: Harvard University Press, 1990).
chronicled the way that traditional business enterprises coordinated by market forces came to be
overshadowed by sprawling corporate bureaucracies administered by untold numbers of salaried
managers. While the individual entrepreneur making his way in the market did not entirely
disappear in Chandler’s narrative, he emphatically believed that “the managerial revolution” was
the real story of modern capitalism.
These managers, Chandler argued, took over the “coordination and integration of the
flow of goods and services from the production of the raw materials through the several
processes of production to the sale to the ultimate consumer.” Not coincidentally, these same
managers often presided over the creation of vast industrial enterprises characterized by both
vertical and horizontal integration. The resulting “managerial hierarchies” proved more effective
than markets in allocating goods and resources. In the process, “the visible hand of management
replaced the invisible hand of market forces where and when new technology and expanded
markets permitted a historically unprecedented high volume and speed of materials through the
processes of production and distribution.”3
Chandler’s preoccupation with the rise of modern management owed much to his
exposure to Talcott Parsons, and by extension, Max Weber. Like Robert Wiebe, whose landmark
The Search for Order told a parallel story, Chandler put bureaucratic rationality and large-scale
organizations at the center of his narrative.4 The historian Louis Galambos dubbed the work of

Chandler, Wiebe, and others part of a new “organizational synthesis,” which offered a new way
of understanding the sweeping economic changes of the late nineteenth and early twentieth
centuries. In the work of Chandler, Wiebe, and others, “formal, hierarchical structures of
authority” came to dominate the nation. “America’s rendezvous,” wrote Galambos, “was not
with the liberal’s good society. It was with bureaucracy.”5
By the 1980s, the organizational synthesis was less the cutting edge than a foil for the
ascendant field of social history. Disciples of history “from the bottom up” had little patience for
Chandler’s blithe disregard of labor, much less his seemingly celebratory account of big business
– though this dismissal, as Richard John has argued, overlooked much that was progressive in
Chandler’s writings. Likewise, the cultural historians who succeeded them had no interest in
Chandler’s work, which largely disregarded the power of ideas. For these reasons, Chandler’s
work had limited resonance inside the mainstream historical profession, even if crude
simplifications of his arguments soon surfaced in history textbooks. 6
But Chandler was hardly ignored and forgotten among those who studied the history of
capitalism before it went by that name. In business history, never mind several allied disciplines,
Chandler attracted a number of adherents, many of whom produced works that echoed and
elaborated points he had first articulated. His students and colleagues and collaborators,
particularly at Harvard Business School, produced a range of work that can fairly be described as
“Chandlerian” in its approach to the history of modern business enterprise. Works by Thomas

McCraw and Richard Tedlow are typical of a historiographical tradition that built upon, rather
than challenged, Chandler’s ideas.7
So, too, did works by scholars who challenged or revised Chandler’s findings. Scholars
like Thomas Cochran sought – largely unsuccessfully – to argue that the more critical phase
came earlier, before large, hierarchical corporations populated the economic landscape. Still
others, like Philip Scranton, assailed Chandler for exaggerating the importance of the
bureaucratic corporations of the late nineteenth century, highlighting instead the continuing
vitality of smaller firms in the late nineteenth and early twentieth centuries. Sociologist Neil
Fligstein argued that the rise of large, bureaucratic corporations had little to do with efficiency
and everything to do with attempts to control competition. Still others have raised questions
about the contemporary relevance of Chandler’s model, given the degree to which bureaucratic
firms have become increasingly obsolete and inefficient since the 1970s. The economist Richard
Langlois, for example, has argued that the large bureaucratic organizations hailed by Chandler
were but a temporary expedient, a product of an “imbalance” between new technologies and old
markets.8
Other scholars have expressed skepticism as to whether the corporate bureaucracies were
all that rational or efficient. If Chandler viewed the managerial revolution from a high altitude,
historians like Walter Licht examined their operation on the ground, finding plenty of human
conflict, infighting, face-to-face negotiation, and other behavior supposedly banished by the
7 See, e.g., Thomas K. McCraw, Prophets of Regulation: Charles Francis Adams, Louis D. Brandeis, James M. Landis, Alfred E. Kahn (Cambridge, Mass.: Harvard University Press, 1984); Richard S. Tedlow, New and Improved: The Story of Mass Marketing in America (New York: Basic Books, 1990); Tony A. Freyer, Regulating Big Business: Antitrust in Great Britain and America, 1880-1990 (New York: Cambridge University Press, 1992). 8 Philip Scranton, “Diversity in Diversity: Flexible Production and American Industrialization, 1880-1930,” Business History Review 65 (Spring 1991), 27-90; Philip Scranton, Endless Novelty: Specialty Production and American Industrialization, 1865-1925 (Princeton, New Jersey: Princeton University Press, 1997); Richard M.

managerial revolution. This idea – that hierarchical firms rarely function as smoothly or
efficiently as Chandler imagined – received its most sustained treatment in Richard White’s
recent Railroaded: The Transcontinentals and the Making of Modern America. At least in the
case of these especially inept enterprises, White found little evidence that they acted as
“harbingers of order, rationality, and effective large-scale organization.” They were, he
concluded, little more than a band of “inefficiently, costly, dysfunctional corporations.”9
Most of these criticisms have merit, but they tend to simultaneously replicate a number of
biases inherent in Chandler’s work. For example, most skeptics of Chandler tend to retain the
firm – whether large or small, hierarchical or flat, efficient or inept – as the primary unit of
analysis. Moreover, a good number of Chandler’s critics tend to retain the focus on bureaucracy
that was so central to the organizational synthesis. These scholars may not be “children of Max
Weber,” as Richard White aptly described Chandler and Wiebe. Nor are the bureaucracies they
study necessarily rational or efficient. But by remaining wedded to an intellectual tradition that
made bureaucratic rationality the sine qua non of modernity, these historians remain prisons of
the original organizational synthesis.10
Those scholars who broke decisively with Chandler’s focus on large, bureaucratic
corporations have sought to reinstate markets to their privileged position within the history of
American capitalism. While much of this scholarship, particularly the work of Philip Scranton,
was a useful corrective, it runs of the risk of overlooking other “coordinating mechanisms” that
occupy fall “beyond markets and hierarchies,” to use the felicitous phrasing of Naomi
Lamoreaux and her collaborators. In an influential article published in the American Historical

Review, Lamoreaux, Daniel Raff, and Peter Temin sought to subsume Chandler’s ideas within a
far more expansive – and far less teleological – framework for understanding the evolution of the
capitalist economy. In particular, they sought to push historians and economists to recognize the
role of “long-term relationships” as a means of addressing problems with coordination and
imperfect information.11
This was long overdue. But this was not, obviously, the last word on the subject. In the
spirit of Lamoreaux’s proposal, I want to suggest yet another way of understanding the
monumental economic changes of the late nineteenth and early twentieth centuries. This means
contemplating some unappreciated, often invisible means of coordinating economic activity.
The mechanisms I have in mind relied on a very different set of social relations than competition
(markets) and commands (hierarchies). They depended instead on cooperation, though they
invariably engendered intense conflict between different classes and interest groups battling for
supremacy in the second industrial revolution.
The development that I wish to put forward today can be summarized in one word:
standardization. This idea, which in most basic form simply means “making things the same,” is
an elusive, but extraordinarily important part of the story that Chandler and his critics have
identified, even if it largely missing from existing accounts of the second industrial revolution.
Standardization is rarely, if ever, the work of a single organization, even if a standard may
initially originate within an individual firm, trade association, or other specific, circumscribed
location. Rather, standardization, by one definition, is “a process of constructing uniformities
across time and space, through the generation of agreed-upon rules.” This process, which is

Raff, eds., Coordination and Information: Historical Perspectives on the Organization of Enterprise (Chicago: University of Chicago Press, 1995) and Naomi R. Lamoreaux, Daniel M. G.

inherently social, can be conceived as “the meeting of numerous parties with the aim of
obtaining legitimate coordination, comparability, and compatibility across contexts.”12
This kind of uniformity should not be confused with the internal standards of a single
firm or business. Take, for example, the system of interchangeable parts that the French
developed in the late eighteenth century, and the Americans commercialized in the nineteenth
century. In this system – dubbed the “American system – a firm that builds guns using standard
parts: if one part breaks, an identical part can be substituted. This is an internal standard that is
peculiar to a single firm. But the part may not work on another manufacturers’ guns, because that
other manufacturer is likely using an entirely different set of interchangeable parts. The internal
standard divides as much it unifies. By contrast, the standardization as defined here is a process
by which “sameness” – uniformity” – connects disparate localities, communities, corporations,
markets, and states across space and time.13
Standardization can encompass a wide range of coordinating mechanisms. These include
uniform accounting standards; metrological standards governing units of measurement;
technical standards defining a uniform industrial component; and quality standards that define
various commodities. Such standards, more often than not, gain currency via cooperation, not
competition. They are born out of trade associations, scientific bodies, professional associations,
congresses, and other venues that transcended individual firms. While they help make markets,
they are rarely perfect, even if they solve many problems associated with “asymmetric

For representative works on the sociology of standards, see James Sumner and Graeme J. N. Gooday, “Introduction,” History of Technology 28 (2008), 1-14; Martha Lampland and Susan Leigh Star, Standards and Their Stories: How Quantifying, Classifying, and Formalizing Practices Shape Everyday Life (Ithaca, New York: Cornell University Press, 2009); Lawrence Busch, Standards: Recipes for Reality (Cambridge, Mass.: MIT Press, 2011). 13 Ken Alder, Engineering the Revolution: Arms & Enlightenment in France, 1763-1815 (Chicago: University of Chicago Press, 1997); David A.

information” that have historically vexed relationships between manufacturers, suppliers, and
distributors.14
There is (and was) a paradoxical quality to this process. After all, all standards are born
of local contexts and are initially peculiar to a single, bounded community. This is true of the
inch as it is of the meter, and true of technical standards, from railroad gauge to the uniform
system of screw threads that I will discuss shortly. The challenge, then, that any historian of
standards faces is to document how a standard becomes the standard: how, in other words, it
moves from something particular to something that has some claim to universality, even if that
claim is contested and contingent.
This process does not, for the most part, take place within the firms and hierarchies
beloved by Chandler. Rather, it is in the cumulative acts of adoption within a community or
network that invest standards with power as coordinating mechanisms. This concept, which
legal theorist David Singh Grewal has dubbed “network power,” makes possible a recognition
that the astonishing logistical and administrative challenges generated by the second industrial
revolution required much more than cadres of middle managers capable of coordinating the
14 There is a small but growing literature on the economics of standards. The best known works relate to the so-called “path dependence” literature. See, for example, Paul A. David, “Clio and the Economics of QWERTY,” American Economic Review 75 (1985), 332-337 and “Why Are Institutions the ‘Carriers of History’?: Path Dependence and the Evolution of Conventions, Organizations, and Institutions,” Structural Change and Economic Dynamics 5 (1994), 205-220, as well as the essays in Pierre Garrouste and Stavros Ioannides, eds., Evolution and Path Dependence in Economic Ideas: Past and Present (Northhampton, Mass.: Edward Elgar, 2001) . But there is also a robust literature in economics on standards and kindred subjects that provides more direct insights into the ways that standards can function as coordinating mechanisms. See, e.g., Yoram Barzel, “Measurement Cost and the Organization of Markets,” Journal of Law and Economics 25 (1982), 27-48; Charles Kindleberger, “Standards as Public, Collective, and Private Goods,” Kyklos 36 (1983), 377-396; Sanford V. Berg, “The Production of Compatibility: Technical Standards as Collective Goods,” Kyklos 42 (1989), 361-383; David A. Paul and Shane Greenstein, “The Economics of Compatibility Standards: An Introduction to Recent Research,” Economics of Innovation and New Technology 1 (1990), 3-41; Christiano Antonelli, “Localized Technological Change and the Evolution of Standards as Economic Institutions,” Information Economics and Policy 6 (1994), 195-216; Lawrence Busch, “The Moral Economy of Grades and Standards,” Journal of Rural Studies 16 (2000), 273-283; Olivier Fabereau, Olivier Biencourt, and François Eymar-Duvernay, “Where Do Markets Come From? From (Quality) Conventions!” in Olivier Favereau and Emmanuel Lazega, eds., Conventions and Structures in Economic Organization: Markets, Hierarchies, and Networks (Northampton, Mass.: Edward Elgar, 2001), 213-252; Yoram Barzel, “Standards and the Form of Agreement,” Economic Inquiry 42 (2004), 1-13.
movement of goods and services. Standardization required the collaboration of managers,
engineers, scientific bodies, professional associations, and entrepreneurs from firms large and
small. It was a collective undertaking that, frankly, dwarfed the logistical and operational
challenges faced by individual firms. While it is now inextricably entwined with globalization,
standardization in the nineteenth century was something that took place within national
borders.15
Given Chandler’s obsessive focus on the firm, it perhaps understandable why he
dedicated but a few pages to standardization in The Visible Hand. But he was hardly alone in
relegating standardization to playing a minor role: many works in business history and the
history of technology that cover the late nineteenth and twentieth century barely mention
campaigns for standardization. Only a few scholars over the past few decades – David Noble and
Steve Usselman, most notably -- have acknowledged the centrality of standards and
standardization; a few others have taken up individual campaigns for standardization of track
gauge, for example, but these narrower works do little to establish a larger explanatory
framework in which standardization takes a central place.16

See Scranton and Fridenson, Reimagining Business History (Baltimore: Johns Hopkins University Press, 2013), 160-165.
It is easy, of course, to overlook standards and standardization. As one sociologist has
ruefully observed, “standards and standardization are such widespread and omnipresent features
of modernity that, ironically, their precise…significance stands at risk of vanishing out of sight.”
This combination of ubiquity and banality is, of course, one reason they are both exceedingly
powerful and simultaneously invisible. As another theorist of standards and standardization has
noted, “successful standards, if they are noticed at all, simply appear as authoritative, objective,
uncontroversial, and natural. In short, they are “recipes for reality.” But like most recipes, they
recede from memory once the finished project is in hand. Little wonder they have received so
little attention in historical circles. 17
That is now beginning to change, thanks to the work of Craig Murphy and JoAnne Yates
as well as Andrew Russell, whose book on the historical origins of “open standards” examines
these efforts to craft industry-wide standards beginning in the late nineteenth century. “By
defining standards,” writes Russell, organizations dedicated to setting standards “facilitated the
existence of multiple sources of supply and thus provided a means for small- and medium-sized
industrial firms to avoid the specter of monopoly.” They were, in other words, a powerful means
of coordinating economic activity without resorting to the need for the hierarchical organization
of large firms integrated along vertical and horizontal lines.18
But this does not mean that standards had no relevance for Chandlerian firms. Many of
these corporations, particularly those born in the merge and acquisition wave of the late
nineteenth and early twentieth centuries, consisted of numerous formerly independent firms that
17 Timmermans and Epstein, “A World of Standards but Not a Standard World,” 84; Andrew L. Russell, Open Standards and the Digital Age: History, Ideology, and Networks (New York: Cambridge University Press, 2014), 16. 18 Craig N. Murphy and JoAnne Yates, “Charles Le Maistres: Entrepreneur in International Standardization,” Enterprises et Histoire 51 (June 2008), 10-27; Craig N. Murphy and JoAnne Yates, The International Organization for Standardization (ISO): Global Governance through Voluntary Consensus (New York: Routledge, 2009); Russell, Open Standards, 26.
were forcibly consolidated under a single set of upper managers. The phrasing used by Richard
White to describe the transcontinentals – “giant corporations employing thousands of men [that]
were less tightly centralized organizations than collections of fiefdoms” – accurately describes
any number of the large, horizontally and vertically integrated behemoths of the era. These
amalgamations had to operate in some semblance unison. But if each of the once-independent
component corporations used different standards – as they often did – coordination within the
resulting vertically or horizontally integrated firm could prove immensely difficult, if not
impossible.19
The individuals who secured the adoption of standards, both within firms and without,
tended to be familiar with the literal nuts and bolts of the second industrial revolution. They
were often engineers, scientists, entrepreneur or some combination of these. These individuals –
astonishingly influential people like the machine-tool savant William Sellers, the engineer
Robert Briggs, or the chemist Charles Benjamin Dudley – do not appear in Chandler’s account.
And no wonder: these individuals occupied niches outside the big, leading industrial firms, or if
they did, did not perform conventional managerial roles. Rather, they operated in the interstices
of an economy increasingly defined by larger, hierarchical corporations, rather than within those
institutions. But that did not mean they lacked power. Far from it.
Indeed, while the “managerial revolution” has much to recommend it as an explanatory
device for a constellation of economic transformations in the Gilded Age and Progressive Era, it
may be useful to consider whether there was an equally important and no less essential
“engineering revolution” that took place alongside of it. This concept, which is borrowed from
works by historians like Steve Usselman and the sociologist Yehouda Shenhav, offers a way to
19 White, Railroaded, 236. On corporate consolidation in the late nineteenth century, see Naomi R. Lamoreaux, The Great Merger Movement in American Business, 1895-1904 (New York: Cambridge University Press, 1985).
broaden our understanding of the monumental transformations of business that took place in the
late nineteenth and early twentieth centuries.20 Standardization was one aspect of this technical
revolution, and a particularly useful way to grasp its many layers, given the sheer number and
diversity of firms, entrepreneurs, scientists, engineers, managers, and others who hammered out
the first technical standards. But this will necessarily require that historians spend more time
reading through the papers of individuals and institutions who operated outside the organizations
that Chandler identified as central to the story.
This will also help rectify one of the most significant shortcomings of Chandler’s work:
his technological determinism. In almost all of his scholarship, Chandler referred to
“technological imperatives” that mysteriously, if inexorably, gave rise to the managerial
revolution. Chandler left him himself open to this charge in no small part because he failed to
actually see the transformation he was describing from the standpoint of the engineers and
mechanics who built – and yes, standardized – the industrial infrastructure that made the
managerial revolution possible in the first place.21 This was certainly true of the most visible
technological icons of the era: the locomotive, telegraph, and steam engines. There is a history
to the standardization of all of these technologies. But I want to focus on something far more
banal, hidden, and unexceptional in order to highlight the centrality of standardization to the rise
of the modern, corporate economy: screw threads.
Please understand that by “standard screw threads” I am referring to something different
from ordinary screws. There is no overriding reason to standardize ordinary wood screws: slight
20 Usselman, Regulating Railroad Innovation; Yehouda Shenhav, Manufacturing Rationality: The Engineering Foundations of the Managerial Revolution (New York: Oxford University Press, 1999). See also Noble, America by Design. 21 On Chandler’s technological determinism, see Usselman, “Still Visible” and David A. Hounshell, “Hughesian History of Technology and Chandlerian Business History: Parallels, Departures, and Critics,” History and Technology 12 (1995), 205-224; Thomas J. Misa, “Retrieving Sociotechnical Change from Technological Determinism,” in Merritt Roe Smith and Leo Marx, eds., Does Technology Drive History?

variations in the thread mean nothing when screws are used to connect two pieces of wood. Far
different are screw threads that connect two pieces of metal together: a screw bolt and a nut, for
example, or a screw that connects to a thread bored into a larger piece of metal. In order for
these to fit together without stripping the metal, or without coming loose, the difference between
them is extraordinarily small – sometimes as little as 1/5000th of an inch., as one technical report
from the 1880s observed. This need for precision would only increase as screws and other
comparable fastenings came to be used on machines such as cars and airplanes where vibrations
could easily loosen poorly made fittings.22
Though screw technologies date to ancient times, precision screw threads only became
possible in the eighteenth century, when French screw lathes first came into use. But these
remained primitive contraptions, and it fell to British mechanics such as Henry Maudslay and
Americans such as David Wilkinson to turn these into machines into something capable of
producing reliable, precise nuts and bolts. For the uninitiated, a lathe is basically a potter’s wheel
turned on its side, where you turn or spin a cylindrical object and cut into it using tools that are
like teeth of hardened steel. The early screw lathes used what is known as a “master screw” to
transmit a regular cut to an unfinished bolt. By fiddling with the gears that connected the master
screw and the blank bolt, a mechanic could effectively cut the thread in a regular fashion,
guaranteeing a certain pitch. These lathes, while originally used to cut screw threads alone, were
22 George M. Bond, Standards of Length and Their Practical Application (Hartford: Pratt and Whitney Corporation, 1887), 71. The best single work on screw threads remains Bruce Sinclair, “At the Turn of the Screw: William Sellers, the Franklin Institute, and a Standard American Thread,” Technology and Culture 10 (1969), 20-34. Sinclair also discusses industrial standardization more generally in A Centennial History of the American Society of Mechanical Engineers, 1880-1980 (Toronto: University of Toronto Press, 1980), 46-60. The only other studies of screw threads focus on European standards for scientific instruments. See Randall C. Brooks, “Standard Screw Threads for Scientific Instruments. Part 1. Production Techniques and the Filiere Suisse,” History and Technology 6 (1988), 59-76 and “Standard Screw Threads for Scientific Instruments. Part 2. The British Association Screw Gauge,” History and Technology 6 (1988), 45-59.
also used to cut pipe threads; indeed, the two branches of machine shop practice are closely
related to one another.23
In the nineteenth century, another method of cutting threads became commonplace using
what are known as taps (which cut the threads inside nuts) and dies (which cut the threads on the
bolts or actual screws). Both taps and dies could be used by hand as well as in machines that
functioned like drills. This new approach was somewhat simpler, and more compatible with the
needs of mass production. In the case of the lathe, the cutting tool remained stationary while the
blank spun on its axis. By contrast, The difference between this approach and the screw lathe lay
in was that here the blank bolt or nut would be held stationary while the tap or die cut away the
metal. A lathe, by contrast, spun the blank while the cutting tool remained relative stationary.
Machine shops cut nuts and bolts according to their own idiosyncratic traditions or
standards. This in theory enabled the various pieces to work together. They did, up to a point.
But – and here’s the important part – the metal screw and bolts that one workshop produced were
incompatible with those produced elsewhere. If you bought an instrument or machine held
together by screw threads, you would need to go back to the original workshop for repairs. In all
likelihood, a machinist would have to craft an entirely new thread from scratch, something that
took hours to do under the best of circumstances.
What was true of screws, nuts, and bolts was true of all metal parts as the industrial
revolution gathered steam. In the early to mid-nineteenth-century United States, manufacturers
produced an ever-greater number of products, from reapers to sewing machines to clocks. For
the most part, these were disconnected: it mattered little if one firm made goods to one set of
internal standards, while other firms followed their peculiar standard. This babel of

manufactured goods would remain common throughout the rest of the century, with small,
specialized manufacturers churning out goods made of parts that, while often interchangeable
with other parts produced by any given firm, did not resemble the corresponding parts produced
by other firms.24 A survey of standardization made by the engineer James See in 1888 thus
detailed an astonishing degree of variation in, among many other things, shoes, wrench squares
for water cocks, dental tools, braces and bits, roller skate wheels, sections of rolled iron, locks,
chain pumps, printers’ chases, fireplace mantels and grates, envelopes, bricks, and others.
Yet as See acknowledged, standardization had taken place in a number of key
components, with screw threads the focus of the very first campaigns for technical standards. To
understand why this happened, it is essential to understand that when we speak of “technology”
during the second industrial revolution, we are increasingly talking about a system – elaborate
concatenations of different technologies -- rather than a collection of discrete, disconnected
machines. These systems could be modest, even banal: the networks of pipes that funneled
natural gas, water, oil, and steam from one place to another. Far more elaborate, and visible,
were the railroads, which assumed astonishing levels of complexity and geographical breadth in
the nineteenth-century Untied States. The railroad contained systems within systems many times
over; it was, as Chandler recognized, a technological network that demanded new ways of doing
business.25
Large, sprawling technological systems built on connections are peculiarly vulnerable to
failure: a single loose bolt can halt a train, and by extension, an entire railroad. Likewise, the

On the continuing importance of batch production and the barriers to standardization, see Philip Scranton, Endless Novelty. 25 On this idea generally, see James R. Beniger, The Control Revolution: Technological and Economic Origins of the Information Society (Cambridge: Harvard University Press, 1986); Thomas P. Hughes, “The Evolution of Large Technological Systems,” in Wiebe E. Bijker, Thomas P. Hughes, and Trevor Pinch, eds., The Social Construction of Technological Systems: New Directions in the Sociology and History of Technology (Cambridge, Mass.: MIT Press, 2012), 45-76.
safety of the entire system is only as good as the connections that keep the parts in play. Bad
pipe threads could lead to natural gas explosions; steam boilers could detonate – and did. The
lack of standardized parts amplified the risks of this happening because a lack of uniformity
rendered it impossible to know, for example, if the strain that one bolt or thread could withstand
might result in a catastrophic explosion elsewhere. And even if the breakdown was not
dangerous, it was immensely inconvenient, with repairs requiring a bespoke approach to the
problem. Factor in the fact that some of more complex machines in these systems – locomotives,
for example – had thousands of bolts and couplings – and potential problems could multiply
exponentially.26
A lack of standards also frustrated the expansion of existing systems, or the absorption of
competing systems. This became particularly imperative in the closing decades of the nineteenth
century, when a burst of corporate mergers put many formerly independent firms under common
management. Dozens of firms that had formerly operated independently now had to move in
unison. Technical standards could, in theory, facilitate this kind of integration as well as foster
the centralization desired by modern management. This was particularly the case with the
railroads, where a lack of standardization frustrated efforts at system-building for much of the
nineteenth century.
The first screw thread standards appeared in Great Britain in the city of Manchester,
home to that nation’s machine tool industry. Credit for the idea goes to a machinist and
industrialist named Joseph Whitworth who had trained in Henry Maudslay’s workshop. In an
address to the Institution of Civil Engineers in 1841, he observed that the rail and steamship
companies had to have as many different tools on hand as they had suppliers of screws.
26 On standardization generally on the railroads, see Usselman, Regulating Railroad Innovation; Albert J. Churella, The Pennsylvania Railroad, Volume 1: Building an Empire, 1846-1917 (Philadelphia: University of Pennsylvania Press, 2012), 578-581.
Whitworth attacked this “want of uniformity,” but recognized that there was no obvious
candidate. In fact, surveying the screw threads in use, he found “instead of that uniformity
which is so desirable, a diversity so great as almost to discourage any hope of its removal.”27
Rather than propose an entirely arbitrary standard, Whitworth gathered sample screw
bolts from around the nation and measured them. He then averaged his findings, arguing that
this would constitute a kind of “compromise, all parties consenting got adopt a medium for the
sake of common advantage.” In short, almost every one would need to alter their screw threads
to make this system work, but most changes would be a matter of moving to the middle, rather
than forcing a radical break with past practices. Whitworth’s system caught on in Britain, thanks
in part to the fact that Whitworth became the exclusive supplier of most of the gauges, taps, and
dies used to make Whitworth screws (and got very rich doing so). Whether this was
Whitworth’s intent from the beginning is difficult to divine, though one prominent machinist in
the United States believed that the 55 degree angle, which required complex machinery to cut,
“was originated by Mr. Whitworth with…the view of keeping the business of supplying the
world in his own hands…by giving an angle so difficult to be dealt with that people would prefer
to come to him for their screw gear…”28
Regardless of Whitworth’s motives, his standard never caught on in the United States,
even if it has some adherents. Instead, machinists continued using a bewildering array of
threads. These might vary by pitch (the number of threads per inch) in strange ways: a single
5/8th inch bolt might have 11 threads, or 11 ½ or 12 or even 11 ⅓ threads per inch. And that was
27 Joseph Whitworth, “A Paper on an Uniform System of Screw Threads,” in Miscellaneous Papers on Mechanical Subjects (London: Longman, Brown, Green, Longmans, and Roberts, 1858), 30; A. E. Musson, “Joseph Whitworth and the Growth of Mass-Production Engineering,” Business History 17 (1975), 109-149; Norman Atkinson, Sir Joseph Whitworth: ‘The World’s Best Mechanician (Phoenix Mill, Gloucestershire: Sutton Publishing, 1996), 129-133. 28 Whitworth, Miscellaneous Papers, 30; George R. Stetson, “Standard Sizes of Screw Threads, Transactions of the American Society of Mechanical Engineers 1 (1880), 6.
just the pitch. The depth of the groove might vary, as would the angles of both the thread and the
groove. The American Railway Times, writing in 1859, bemoaned that “instead of that
uniformity which is so desirable, a diversity so great as almost to discourage any hope of its
removal.” Likewise, in a number of editorials published in the early 1860s, Scientific American
observed that “if there is any one thing in the transactions of the machine-shop more
incomprehensible than another, it is the want of some settled size or number for screw threads.”29
Yet the machine tool and metal-working industries resisted calls to standardize. This
may have been a function of what one writer later described as the alleged “selfishness of
manufacturers, who prefer their own fractional threads in order that repairs and reduplications
must come from them.” There is likely some truth to this claim: in the closing decades of the
nineteenth century, many manufacturing firms resisted calls of industry-wide standardization,
believing that common standards would lead to ruinous cost-cutting. Differentiation, by
contrast, permitted companies to flourish in their own niches, largely insulated from competitive
pressures.30
Absent some government edict, which would have been next to impossible to enforce,
standardization would require a rather unusual mix of individuals and institutions to get it off the
ground. The city of Philadelphia, arguably the center of the nation’s machine tool and metal-
working trades at this time, came to play the most significant role. A number of key firms had
their headquarters here, including the Baldwin Locomotive Works. The people behind these
firms often belonged to the same families, making collaboration more possible. Many came
from Quaker families, and they embodied that religion’s fetishization of consensus over conflict. 29 “Proportions for Screw Threads,” American Railway Times, 21 May 1859, 11, 21; “The Pitch of Machine Screws,” Scientific American, 13 December 1862, 376; “The Size and Pitch of Machine Screws,” Scientific American, 3 January 1863, 6; “The Pitches of Screw Threads,” Scientific American, 10 October 1863, 233; 30 “The Standard Screw Threads,” Scientific American, 9 February 1884. For an interesting theoretical take on these issues, see Stanley M. Besen and Joseph Farrell, “Choosing How to Compete: Strategies and Tactics in Standardization,” Journal of Economic Perspectives 8 (Spring 1994), 117-131
Moreover, almost all had some affiliation with the Franklin Institute, a private organization
dedicated to disseminating technical knowledge that had far more influence than any other such
organization, never mind the federal government itself.31
Philadelphia’s industrial community, in other words, was well suited to craft a standard.
In fact, two of its leading technical minds, Robert Briggs and William Sellers, promulgated some
of the first technical standards in the nation. Briggs, who spent the 1840s and 1850sacquiring
experience building iron pipes, came to Philadelphia in 1860 to become the Superintendent and
Engineer of the Pascal Iron Works, makers of iron pipes and fittings. Briggs was the
consummate modernizer, someone who, as a posthumous sketch of the man observed, brought
“order out of chaos.” His most lasting contribution was the adoption of a regular, standard
system of pipe threads, couplings, and valves – the eponymous Briggs system that governs our
pipes and tubes today. This standard originated in the early 1860s at the Pascal Iron Works,
which under Briggs leadership soon became the nation’s largest manufacturer of pipes,
couplings, and fittings. It was in a position where it could easily set the standard, in that other
firms had less to gain by going their own way. If they wished to connect to pipe manufactured
by Briggs, they needed to adhere to his standard. And they did, though this took many years.32
But I want to focus today another standard bearer of modernity named William Sellers.
A mechanical prodigy, Sellers founded a machine tool firm that exercised a disproportionate 31 Bruce Sinclair, Philadelphia’s Philosopher Mechanics: A History of the Franklin Institute, 1824-1865 (Baltimore: Johns Hopkins University Press, 1974); A. Michael McMahon, “‘Bright Science’ and the Mechanic Arts: The Franklin Institute and Science in Industrial America, 1824-1976,” Pennsylvania History 47 (October 1980), 351-368; Stephanie Morris, The Franklin Institute and the Making of Industrial America (Bethesda, Maryland: CIS Academic Editions, 1987). On the centrality of the machine-tool industry to solving technological problems, see Nathan Rosenberg, “Technological Change in the Machine Tool Industry, 1840-1910,” Journal of Economic History 23 (December 1963), 414-443. 32 William J. Baldwin, “On Standard Cast-Iron Fittings,” Transactions of the American Society of Mechanical Engineers 4 (1882),. 274-287; George M. Bond, “Standard Pipe and Pipe Threads,” Transactions of the American Society of Mechanical Engineers 7 (1885), 311-327. The Briggs standard likely began somewhat earlier in 1846, though it wasn’t systematized until the 1860s See the posthumous paper by Briggs, “American Practice in Warming Buildings by Steam,” Paper No. 1842, Minutes of the Proceedings of the Institution of Civil Engineers 71 (1883), 95-123; “Robert Briggs,” Journal of the Franklin Institute 115 (1883), 229-236.
influence relative to its size. One contemporary described him as the “greatest tool builder of his
day and generation”; none other than Joseph Whitworth labeled him “the greatest mechanical
engineer in the world.” Sellers had his own firm in Philadelphia. He also founded the Edge Moor
Iron Company in 1868, which dominated the fabrication of the iron and steel components used in
bridges and other large-scale projects; it was the largest such plant in the world at the time. 33
Sellers had a fetish for uniformity. In the mid-nineteenth century, most industrialists who
built metal structures or machines tended to paint them different colors. Sellers, by contrast,
adopted a “dull lead tint…known as ‘machine gray.” Long before “form follows function”
became the rallying cry of modern architecture, Sellers designed his machines with an eye to the
precise role they would play. His “method of design,” one contemporary noted, was the
“adaptation of the forms of his machine to the strains to be carried by them.” This preoccupation
with efficiency went hand in hand with an obsessive drive to control those who carried out his
wishes. The factory itself was a machine. “He knew how to give an order and exact obedience,”
recalled one associate after his death, “and only to those who showed the capacity to obey did he
extend the authority to direct the management of his affairs, while over all he never failed to
exercise a masterly control.” Sellers went on to become president of the Midvale Steel
Company, a corporation best known as the site of Frederick Winslow Taylor’s experiments in
scientific management. Recent scholarship has suggested that many of Taylors ideas in fact
originated with Sellers.34
What does this have to do with screw threads? Understand that in a world where every
nut and bolt – every screw thread coupling – was sui generis, skilled labor wielded astonishing

levels of control over the operation and maintenance of the nation’s machines. By contrast, if a
system of uniform screw threads could be established and mass-produced, building --- never
mind fixing – those machines would require far less in the way of skilled labor. It would also
move the locus of power away from the shop floor toward management. Indeed, from the
perspective of an industrialist like William Sellers, a uniform system of simplified screw threads
offered a means of “masterly control,” making his shop floor legible and transparent.
This helps explain the system of screw thread standards that Sellers presented in 1864 at
the Franklin Institute. Rather conveniently, Sellers was also the president of the Franklin
Institute, virtually guaranteeing that whatever he proposed would find a sympathetic audience.
Sellers rejected the Whitworth standard, which he found wanting in several respects, particularly
the amount of skill and special machinery that it entailed. The angle of 55 degrees, for example,
“is a difficult one to verify,” argued Sellers. The Whitworth Standard required special tools,
special gauges, and a great deal of expertise. By contrast, the committee appointed by Sellers to
review his own proposal concluded that the Sellers thread “would enable any intelligent
mechanic to construct it without any special tools…” This echoed Sellers’s own position that
“the problem of the day is not only how to secure more good workmen, but how to enable such
workmen as are at our command to do good work…In other words, the attention of engineers is
constantly directed to so perfect machine tools as to utilize unskilled labor.” 35
But there was more to this than control over the shop floor. The standard that Sellers
proposed was already in use at his own machine tool factory. Whatever the many advantages of
his standard – and there were many – other manufacturers would need to conform to his standard
and assume the burden of retooling their establishments at their own expense. To some extent

they were willing to do so, if even this meant sacrificing the advantages of their own peculiar
systems of threads. Charles T. Parry, the Superintendent of the Baldwin Locomotive Works,
observed that while “fine threads were best adapted for locomotive purposes, as they are more
permanently secured when screwed up, than the coarse threads,” nonetheless conceded that “we
would be glad to find a coarser thread acceptable, and would be willing to advocate it if by that
means only, uniform standard threads could be adopted.” This pragmatism would become more
common in succeeding years. As the engineer George See argued in the 1880s, “it is certainly
better that these things should be uniform, than that a few should be better and many worse, and
all different. Uniformity in such case is of itself a superior merit.” 36
But who, precisely, got to choose which standard should prevail? In the case of screw
threads, not everyone was convinced that the Sellers plan was best. Critics included the
formidable Robert Briggs, who advocated a modified version of the Whitworth system, and
strenuously pressed his case within the halls of the Franklin Institute. But he was fighting an
uphill battle against the president of the institution, and when the matter came to a vote, he lost.37
From here the battle moved to other arenas, including the United States Navy, which created a
board in 1868 to review the competing standards and deem one worthy of universal adoption. In
the course of their investigations, they visited machine shops around the country, gathering
information on the systems in use. Not surprisingly, the report found most of these to be
“entirely without system.” Several establishments used variants of the Whitworth standard, but
with the exception of a single firm, these strayed from the original prescription, intermingling
with other local standards to create what the board disapprovingly classified as “mongrel”
36 Proceedings of the Franklin Institute 79 (1865), 53-56; See, “Standards,” 546. 37 Robert Briggs, “A Uniform System of Screw Threads,” Journal of the Franklin Institute 79 (1865), 111-125.

standards. The board likewise rejected the Briggs standard, largely because it could not be
“scaled up” to encompass larger diameter bolts without sacrificing their ability to withstand
strain. The Sellers system, by contrast, offered the appearance – some might say illusion – of a
natural law, complete with universal constants. It was, the board concluded, a system “which, by
the use of the formula, or equation of the curve representing its law, admits of indefinite
extension.”38
The Navy endorsed the Sellers system, ordering that work done on naval contracts
conform to it, though the government had no further role in implementing the system. Not long
afterward, important professional associations connected to the railroads – the Master Car-
Builders Association and the Master Mechanics’ Association – urged its adoption on its
members. This was imperative by the 1880s. As the Journal of the Franklin Institute noted in
1888, “since the exchanging of cars from one road to another has become so universal, the
necessity for an interchangeable system of bolts and nuts has grown more apparent; and all the
roads are falling into line in adopting the Sellers system.”39 And this might well be the end of the
story, if standardization depended only on the endorsement of a few key interest groups,
corporations, and ostensibly neutral professional organizations like the Franklin Institute. But
that is not what happened. Each turn of the screw, so to speak, lead to consequences that neither
Sellers nor other advocates of standardization could have foreseen.
To the extent that historians of technology contemplate standards, there is often a
presumption that once a standard has been adopted, the rest is easy. Not true. In 1874, the New
York, Lake Erie & Western Railroad adopted the Sellers system, proceeding to furnish a set of
standard taps and dies to each of the machine shops on the line (a tap is a tool used to cut the

thread of a nut; a die is used to cut the actual screw thread on the bolt). In 1876, managers
discovered that nuts fashioned in one shop failed to fit bolts cut at others. Nor would they fit
with the nuts and bolts produced by other corporations’ shops that had also adopted the Sellers
standard.40
What was going on here? Though some of the failures could be chalked up to sloppiness
or failure to adhere to the standard, investigations turned up something more serious. At a
meeting of the Master Car Builders’ Association in 1879 to which William Sellers was invited, a
committee appointed to look into the matter reported that the taps and dies manufactured and
sold to machine shops as the Sellers standard differed in their dimensions. Why? The committee
found that the manufacturers of these standard taps and dies relied on gauges to insure the
accuracy of their wares. But the gauges, when examined, turned to be different as well, and
“although the difference was not great, it was sufficient to prevent the bolts and nuts, made to
conform to them, from interchanging with each other.” As Sellers remarked at the meeting, “the
difficult does not exist in the system of screw threads so much as it does in the matter of the
original standard” – in other words, the definition of the inch. 41
The establishment of such fundamental standards – so-called “metrological standards” --
has usually been viewed, on the rare occasions when it has attracted scholarly scrutiny, as a
prerogative of the nation state.42 But in this instance, responsibility ultimately fell instead to a
single private firm known as Pratt &Whitney. As the leading manufacturer of taps and dies, as
well as gauges used to measure the accuracy of these templates, Pratt and Whitney set out to
create a standard that could be reliably used in commercial work. The details of this are

Stetson, “Standard Sizes of Screw Threads, Transactions of the American Society of Mechanical Engineers 1 (1880), 3-4. 42 See, e.g., James Scott, Seeing Like a State: How Certain Schemes to Improve the Human Condition Have Failed (New Haven: Yale University Press, 1998), 24-27.
technical, involving a remarkable partnership between the astronomer William A. Rogers at
Harvard and machinists at Pratt and Whitney, the most notable of which was George M. Bond.
In order to get to the “bottom” of the matter – to construct a system of screw threads on
something genuinely concrete, a kind of ur-standard. Toward that end, Rogers obtained a
transfer of a copy of the standard yard of the British Imperial Yard on deposit in the “Strong
Room” of the Old Palace Yard in London. This was formerly known as “Bronze 19,” but after a
fire destroyed the original standards, it became known as Imperial Yard No. 1.
In the end, Pratt and Whitney produced several yard measures that were as accurate – if
not more accurate – than those on deposit at the Office of Weights and Measures. They built
entirely new machines to do so, including a machine known as the “Universal Comparator.”
After confirming that the standard on deposit at the Office of Weights and Measures matched its
standards, the company began producing master screw thread gauges that could be sold to
clients. In effect, the nation’s machine shops began coordinating their own production of screws
with gauges guaranteed to match the master gauges – and by extension, the master units of
measure – held in the vaults of Pratt and Whitney. 43 In the succeeding years, within certain
industries – namely, the railroads – screw threads did move toward some semblance of
standardization. But this process was gradual and halting. At the same time, the standardization
of the very unit of measure made possible the distribution of accurate gauges in a range of metal-
working industries, ushering in an age when it became possible to contemplate, if not actually
institute, a more comprehensive set of product standards governing a range of components.

On this episode, see also Richard Staley, Einstein’s Generation: The Origins of the Relativity Revolution (Chicago: University of Chicago Press, 2008), 65-132.
But as it did, it effectively closed the door to another project of standardization that had
become one of the most visible emblems of metrological modernity: the metric system. By the
late nineteenth century, the scientific community had endorsed its adoption, and it seemed as
though Congress might well make the it compulsory, having already legalized its use in 1866.
But the machine tool industry – and in particular, the people involved in making nuts and bolts –
frustrated these efforts. It would not be an exaggeration to say that the reason we do not use the
metric system in the United States is due overwhelmingly to the path dependencies generated by
the humble screw thread.
Coleman Sellers, a cousin and business associate of William Sellers, was one of the more
vocal opponents of the metric system. In a series of broadsides intended for his fellow
mechanical engineers and machinists – “The Metric System: Is it Wise to Introduce It into Our
Machine Shops? – Sellers laid out the case against adoption. His brief against the metric system
was not the backward, provincial mutterings of a xenophobe, but the arguments of a modernizer
who had already chosen a path toward standardization that had, by the 1870s and 1880s, become
irreversible.44 As Sellers noted, “gradually, separate and distinct manufacturing establishments
have come to use the same standards and to make their production interchange one part with
another.” He cited the “screws and fittings for steam, gas and water pipes,” as well as the
standards system of “screw threads for bolts and nuts” promulgated by his cousin. All of the
nation’s machine shops contained tools for crafting these standardized items, all denominated in
terms of the inch. These would need to be replace, as would the dies, taps, gauges, and even the
drawings that served as templates for the various parts.45
44 Coleman Sellers, “The Metric System: Is It Wise to Introduce It into Our Machine Shops?” Transactions of the American Society of Mechanical Engineers 1 (1880), 1-19. 45 Coleman Sellers, “The Metric System in Our Workshops; Will Its Value in Practice Be an Equivalent for the Cost of Its Introduction?” Journal of the Franklin Institute 97 (1874), 381-391.
But it was the deeper, systemic changes that truly posed a problem for the metric
system’s adoption. As Sellers noted, “America has, for the last half century, been striving in its
own way, towards equalization of its standard sizes. The immense railroad industries demand
this. Standard wheels or standard axles – standard fit sizes for both – are all founded on an inch
scale of sizes.”46 These components, from screw threads to railroad car couplings, constituted a
vast, interconnected technical system founded on the inch. Adopting the metric system would
therefore necessitate that every single piece of that system be changed. Change would not be
discretionary. Nor, Sellers noted, would it be cheap. This argument carried the day from the
1870s onward. Throughout it all, the arguments of the mechanical engineers became the primary
stumbling block toward adoption of the metric system. The humble nuts and bolts that knitted
together the ever-growing technical infrastructure of the United States would not – could not –
be readily replaced. And in the ensuring decades, repeated attempts at compulsory adoption of
the metric system would founder on the people, practices, and things rooted in this system. Each
technical standard adopted in the late nineteenth and early twentieth century further entangled
the technological infrastructure of the United States in a deeper set of standards at odds with
much of the rest of the world.
Here, then, was a paradox. As a coordinating mechanism, screw threads worked
exceedingly well within national boundaries, and their very existence highlights an
unappreciated dimension of the second industrial revolution that cannot be understood purely in
terms of markets or hierarchies. At the same time, however, these mechanisms were
increasingly out of step with the coordinating mechanisms devised by other players in an
increasingly global economy. Like the large, vertically and horizontally integrated corporations
that Chandler studied just as they began to disappear, the technical standards born in the second 46 Ibid.
